The clothes are remnants from a brighter time when Bell, a rainbow Afro wig on his head and platform shoes on his feet, strutted through Chicago as a charter member of the ’70s funk revolution whose sound is heavily sampled in rap songs today.

“It was psychedelic from a black perspective,” Bell said.

Bell, 59, designed the cover art for more than two dozen George Clinton and the Parliament Funkadelic albums. Under the name Sir Lleb (Bell backward), he wrote the albums’ liner notes, peppering them with cartoonish drawings, clever puns and names like “Thumpasaurus” and “Funkapus” that remain synonymous with Clinton’s music.
